The last time I looked, it would cost something on the order of $40, and take upto three months to have a single roll processed. Is this consistent with your experience?

You can get a mailer for about 5 or 6 bucks from B&H. Last time I shot a roll of Kodachrome I just brought it down to Longs (California Drugstore chain) and had it back in about a week. Maybe around $7 total. They still sell the Kodachrome 64 in their photo section...I've actually seen T-max 400 on the pegs there also.

Thanks Brad, I'm pretty well stocked on K64. You should shoot it and take it down to Longs...whoever quoted you $40 is trying to pull one over on you.
